Some drugs may alter taste. Biaxin (an antibiotic) can change taste perception.
Also being low in zinc will alter taste by changing the sensitivity of the sense of smell.
Some viral infections can cause a body wide neuropathy. This is usually self limiting and goes away. It can happen after a vaccine too. People vary in viral neuropathic syndromes, some have a mild form and others have severe pain for months/or years.
If you are over 50, I'd suggest you follow NIH guidelines and take some B12 in supplement form every day. Do this on an empty stomach. You may be marginal in B12 levels.
If you do go to a doctor, ask for a serum B12 level in the testing and get the numbers. Lab ranges in US are low, and have not been corrected to the new diagnostic level of 400.
